About Nantz Orthodontics

Phase 1 treatment for young children and a conservative approach that avoided extractions or jaw surgery recommended elsewhere.

Reviews often describe a practice that starts treatment early when needed, with several families noting expanders and phase 1 braces finished in under a year and improvements in breathing or sleep. Many reviewers highlight a cautious philosophy that avoided extractions or jaw surgery recommended elsewhere, including one case where an impacted tooth was corrected without oral surgery. The office is also noted for financing flexibility, including free consultations and interest-free payment plans, and for helping anxious or sensory-sensitive children through treatment with patience and small comforts like choosing retainer colors.
